| 説明 | The Snake River likely got its name from the first European explorers who misinterpreted the sign made by the Shoshone people who identified themselves in sign language by moving the hand in a swimming motion which appeared to these explorers to be a "snake." It actually signified that they lived near the river with many fish.The river is as big as the landscape. Below Hells Canyon Dam, the Snake usually carries more water than the Colorado River through the Grand Canyon. Below the confluence with the Salmon River, flows average 35,000 cfs and often peak over 100,000 when the Salmon is high. Further downstream, the Clearwater and other rivers dump their flows into the Snake River, creating the Columbia River's largest tributary. (The total drainage area is approximately the size of Oregon.)The outstandingly remarkable values of the Wild and Scenic Snake River are scenery, recreation, geology, wildlife, fisheries, cultural resources, vegetation/botany and ecology.Photo by Bob Wick, BLM. The Wild and Scenic Rivers Act provides three levels of river classification: wild, scenic, and recreational.Wild rivers are free of dams, generally inaccessible except by trail, and represent vestiges of primitive America.Scenic rivers are free of dams, with shorelines or watersheds that are still largely primitive and shorelines that are largely undeveloped, but accessible in places by roads.Recreational rivers are readily accessible by road or railroad, may have some development along their shorelines, and may have been dammed in the past. |
